ABR11 1) Silent deploy/configure 2) License Server issue

Hi Community,

1) Question
is there a silent option so deploy ABR Agent silent to the clients and add a backup configuration to the clients?
It would be wonderful if this would work via cmd

2) How can i change License Server on the clients?
Some clients uses DNS Name, i think i would be no Problem, but some Clients had the old ip address, and we had to move to a separate IP-Subnet :(

Thank you.
